Deadlines are firm and will not be extended. -- PUBLICATION -- The proceedings will be published in the Advanced Research in Computing and Software Science (ARCoSS) subline of Springer's LNCS series. The proceedings volumes will appear in gold open access under CC-BY license, so the published versions of all papers will be available for everyone to download from the publisher's website freely from the date of online publication, perpetually. The copyright of the papers will remain with the authors. -- AWARDS -- The strongest papers from the four conferences will be marked as distinguished papers and highlighted in the conference program. From these distinguished papers, the EAPLS, EASST, and EATCS, and the Best Tool Paper Award committees will select the best ETAPS papers. The ETAPS Test-of-Time Award will be granted, recognizing outstanding papers published at ETAPS more than ten years in the past. The ETAPS Rance Cleaveland Test-of-Time Tool Award acknowledges the importance of reliable and well-maintained research tools and the significant effort that their creation and maintenance entails. The Doctoral Dissertation Award will be granted to promote and recognize an outstanding dissertation in the research areas covered by the four main ETAPS conferences. -- SUBMISSION INSTRUCTIONS -- The four main conferences of ETAPS 2027 solicit contributions of the following types. All page limits are given *excluding the bibliography*. * ESOP: regular research papers of max 25 pp, experience reports of max 15 pp, and fresh perspectives providing new insights on programming languages and systems of max 15 pp. For the sake of flexibility, submitted research papers may be formatted in other formats. There is no page limit at the submission time. Please refer to https://etaps.org/2027/esop for more details. * iFS: there are two lengths of papers: long (16pp + 2pp references) and short (8pp + 1pp references). The limits for particular paper categories are: Regular research papers: long; Empirical evaluation papers: long or short; Data showcase paper: short (+ optional appendix up to 6pp); New ideas and emerging results (NIER) papers (visions, reflections): short; Tool papers: long or short (+ optional appendix up to 6pp); * FoSSaCS: regular research papers of max 18 pp. * TACAS: regular research papers, case study papers, and regular tool papers of max 18 pp, tool demonstration papers of max 6 pp. For definitions of the different paper types and specific instructions, where they are present, see the web pages of the individual conferences. All accepted papers will appear in Springer proceedings and have presentations during the conference. A condition of submission is that, if the submission is accepted, one of the authors attends the conference to give the presentation. We plan ETAPS 2027 as an on-site conference. Submitted papers must be in English, presenting original research. They must be unpublished and not submitted for publication elsewhere. In particular, simultaneous submission of the same contribution to multiple ETAPS conferences is forbidden. Submissions must follow the formatting guidelines of Springer's LNCS (use the llncs.cls class) - except for ESOP, see above - and be submitted electronically in pdf through the Easychair author interface of the respective conference. Submissions not adhering to the specified format and length may be rejected immediately. Data availability statement in proceedings papers is mandatory for all ETAPS conference papers. It is to be placed just before the references and does not count into the page limit. ETAPS conferences will use double-blind reviewing (in the case of TACAS and iFS, only for regular research papers). Authors are asked to omit their names and institutions; refer to prior work in the third person, just as prior work by others; not to include acknowledgments that might identify them. ESOP, TACAS and FoSSaCS will use an author rebuttal phase. -- ARTIFACT SUBMISSION AND EVALUATION -- Regular tool paper and tool demonstration paper submissions to TACAS must be accompanied by an artifact submitted shortly after the paper. The artifact will be evaluated, and the outcome will be considered in the paper's acceptance decision. For research paper and case study paper submissions at TACAS, participation in artifact evaluation is voluntary. Authors of papers of these categories may submit an artifact for evaluation after the paper has been accepted. The outcome of the artifact evaluation will not change the paper acceptance decision. ESOP, iFS, and FoSSaCS will accept artifact submissions; however, participation in it is voluntary; the artifact submission deadline is after the paper notification deadline. The outcome will not alter the paper acceptance decision. For ESOP, artifacts may be submitted with an accompanying short 5-page experience report (including a 1-page bibliography) that will appear in the conference proceedings. For specific instructions regarding artifacts, see the web pages of the individual conferences. -- SATELLITE EVENTS (April 10-11, 2027) -- Several satellite workshops and other events will take place during the weekend before the main conferences. -- CITY AND HOST INSTITUTION -- ETAPS 2027 will take place in Copenhagen, Denmark and is organized by the University of Copenhagen, IT University of Copenhagen, and Aalborg University. -- ORGANISERS -- Kim Guldstrand Larsen, Aalborg University Fritz Henglein, Copenhagen University Thomas Troels Hildebrandt, Copenhagen University Andrzej Wąsowski, IT University of Copenhagen Carsten Schürmann, IT University of Copenhagen Boris Düdder, Copenhagen University

[Caml-list] PERR2026 @ CAV/FLOC: Second Call For Papers
[with apologies for cross-postings]
======================================================================
Updated information on: program committee, early registration deadline
======================================================================
SECOND CALL FOR PAPERS/PRESENTATIONS
6th Workshop on Program Equivalence and Relational Reasoning
24 July 2026 at ISCTE campus, Lisbon, Portugal
associated with CAV 2026 at FLOC 2026
======================================================================
Submission Deadline: Friday, 24 April, 2026 (AoE)
Submit at: https://submissions.floc26.org/perr
PERR is an annual international workshop dedicated to the formal verification of program equivalence and related relational problems. It is the 6th in a series of meetings that bring together researchers from different areas interested in equivalence and related questions. PERR 2026 will be a workshop at FLOC 2026, and a satellite event to CAV 2026.
Program equivalence is arguably one of the most interesting and at the same time important problems in formal verification. It is a cross-cutting topic that has attracted the interest of several research communities: the field of denotational (game) semantics, deductive software verification, bounded model checking, specification inference, software evolution and regression testing, etc.
The goal of the workshop is to bring researchers of the different fields in touch and to stimulate an exchange of ideas leading to forging a community working on PERR. It welcomes contributions from the topics mentioned above but is also open to new questions regarding program equivalence. This includes related research areas of relational reasoning like program refinement or the verification of hyperproperties, in particular of secure information flow.
- regression verification
- program equivalence
- equivalence of higher order programs
- product programs, relational calculi
- verification of hyperproperties
- program refinement, refinement calculus
- specification of differences between programs
- inferring semantic differences between programs
- transformation validation
- correct compiler transformations
- automata bisimulation
- AI-supported equivalence checking
- relational properties of AI-based systems
- code equivalence checking in teaching and marking
This is an informal workshop that welcomes work in progress, overviews of more extensive work, programmatic or position papers and tool presentations.
SUBMISSION GUIDELINES
We invite two types of submissions:
- Regular papers. Regular papers should be at most 15 pages (excluding references). They should present original research results, tools, or case studies.
- Extended Abstracts. Extended abstracts should be at most 3 pages (excluding references). They should introduce work that has recently been published or is under review, or work in progress.
Submissions should be made using the PERR 2026 submission site:
Submissions must be a single PDF file, in LNCS format.
The workshop will have informal proceedings, posted on the webpage, and speakers will be asked to consider submitting papers towards a post-proceedings volume.

[Caml-list] WPTE 2026: Call for Papers
WPTE 2026 (affiliated with FLoC 2026 and FSCD 2026 in Lisbon, Portugal)
12th International Workshop on Rewriting Techniques for Program
Transformations and Evaluation (19 July 2026)
Webpage: https://wpte2026.github.io/
Submission: https://submissions.floc26.org/wpte/
Deadline: 22 April 2026
---------------------------------------------------------------------------
The aim of WPTE is to bring together researchers working on
program transformations, evaluation, and operationally-based
programming language semantics, using rewriting methods, in order to
share the techniques and recent developments and to exchange ideas to
encourage further activation of research in this area.
Topics of Interest
---------------------------------------------------------------------------
* Correctness of program transformations, optimizations and translations.
* Program transformations for proving termination, confluence, and
other properties.
* Correctness of evaluation strategies.
* Operational semantics of programs, operationally-based program
equivalences such as contextual equivalences and bisimulations.
* Cost-models for arguing about the optimizing power of transformations
and the costs of evaluation.
* Program transformations for verification and theorem proving purposes.
* Translation, simulation, equivalence of programs with different
formalisms, and evaluation strategies.
* Program transformations for applying rewriting techniques to programs
in specific programming languages.
* Program transformations for program inversions and program synthesis.
* Program transformation and evaluation for Haskell and rewriting.
* Rewriting-based transformations for bidirectional programming and
reversible computation.
Submission Guidelines
---------------------------------------------------------------------------
For the paper submission deadline, a regular paper or extended abstract
of at most 10 pages is required. WPTE 2026 accepts submissions in three
categories:
* Regular paper, reporting on completed work that has not yet been
formally published and is not under submission for formal publication
at another venue (journal, conference, workshop with formal
proceedings).
* Work-in-progress extended abstract, reporting on work in progress.
* Presentation-only extended abstract, a short version of a paper

co-located with NFM 2026 (May 5 - May 7, 2026), Los Angeles, California, USA
International Workshop on Formal Requirements Engineering and Artificial Intelligence
May 4, 2026
co-located with NFM 2026 (May 5 - May 7, 2026), Los Angeles, California, USA
Overview
This workshop explores the intersection of formal requirements engineering and artificial intelligence (AI), addressing a central challenge in modern software and AI system development: how to precisely specify requirements for increasingly complex, heterogeneous, and autonomous systems, and how to verify and validate that such systems meet those requirements.
As AI technologies become deeply embedded in safety and mission-critical domains, from autonomous vehicles to medical diagnostics, financial systems to industrial automation and space exploration, the need for rigorous, formal approaches to requirements is becoming increasingly important. At the same time, traditional requirements engineering methods face new challenges when applied to systems with learning-enabled components, unpredictable behaviors, and emergent properties. The opacity of AI models and the semantic gap between high-level requirements and low-level model inputs and internals create significant impediments to verifying and validating that such systems meet their specified requirements.
The workshop welcomes extended abstract contributions on formal specification languages for AI systems, verification and validation techniques, requirements for trustworthy AI, case studies from real-world applications, and novel applications of AI to requirements engineering itself. We aim to foster dialogue between communities that have traditionally worked separately, building bridges toward more reliable, safe, and trustworthy AI systems grounded in rigorous requirements practices. Extended abstracts can summarize and cite results from recent published paper(s) and/or state your perspective.
Areas of interest include but are not limited to:
- How can we formally specify requirements for systems with learning-enabled components?
- How can formal frameworks capture fairness, safety, robustness and explainability requirements for AI systems?
- How do we verify that AI systems meet their specified requirements?
- What role can AI play in automating requirements elicitation, formalization analysis, and validation?
- How do we bridge high-level requirements and behavior of AI-enabled systems to enable traceability, safety assurance, and certification?
Important dates:
- Submission deadline: March 16, 2026
- Notification: April 3, 2026
- Workshop: May 4, 2026
Paper submission guidelines
We invite extended abstracts of 2-4 pages (excluding references) in LNCS format, https://www.springer.com/gp/computer-science/lncs/conference-proceedings-guidelines. All submissions must be in English and fall into one of the following categories:
- New and Emerging Work: Presents novel research in the focus areas of the workshop. Submissions will be evaluated primarily on "novelty".
- Summary of Recent Results: Presents existing work and highlights its contribution in terms of relevance and impact in the focus areas of the workshop. Submissions will be evaluated primarily on "impact".
Please note that:
- No Formal Proceedings: We welcome submissions of work that has already been presented or submitted elsewhere. No copyright transfer is required; we only request permission to post accepted abstracts on the workshop website.
- Journal Special Issue: Authors of selected accepted abstracts will be invited to submit extended versions for a journal special issue.
All submissions will be reviewed by members of the Program Committee. The paper review process is single-blind, which means that the author identities are not required to be anonymous and are visible to the PC members/reviewers, but reviewer identities are not visible to the authors. No special efforts are required to anonymize content in the paper (such as referencing the authors' prior work).
Policy on the use of Gen AI (same as NFM)
We understand the convenience afforded by the use of generative AI-based large language models to produce text in the submitted manuscript. However, we strongly encourage the authors to check the generated text for factual errors and inconsistencies. We encourage the authors to adopt appropriate standards for citing products obtained using generative AI (such as text, tables, graphics). Use of AI-based coding assistants is permitted, and we encourage authors to disclose the use of such tools as the community may find this scientifically interesting.
Submission will be via the OpenReview link:
To submit a paper on OpenReview, you must first create a profile and log in to the system. Then, navigate to the specific conference or venue's page on OpenReview, find the "Conference Submission" link, and click on it. Fill out the submission form, which will prompt you for paper details like title, authors, abstract, and keywords, before uploading the PDF of your paper.

The Workshop on Termination (WST) traditionally brings together, in an
informal setting, researchers interested in all aspects of
termination, whether this interest be practical or theoretical,
primary or derived. The workshop also provides a ground for
cross-fertilization of ideas from the different communities interested
in termination (e.g., working on computational mechanisms, programming
languages, software engineering, constraint solving, etc.). The
friendly atmosphere enables fruitful exchanges leading to joint
research and subsequent publications.
The workshop is held as part of the 2026 Federated Logic Conference
(FLoC 2026 https://www.floc26.org) and is affiliated with the
13th International Joint Conference on Automated Reasoning
(IJCAR 2026 https://www.floc26.org/ijcar).

Termination and Complexity Competition 2026
http://www.termination-portal.org/wiki/Termination_Competition_2026
Call for Participation
Since the beginning of the millennium, many research groups developed tools for fully automated termination and complexity analysis.
After a tool demonstration at the 2003 Termination Workshop in Valencia, the community decided to start an annual termination competition to spur the development of tools and termination techniques.
The termination and complexity competition focuses on automated termination and complexity analysis for all kinds of programming paradigms, including categories for term rewriting, imperative programming, logic programming, and functional programming. In all categories, we also welcome the participation of tools providing certifiable proofs. The goal of the termination and complexity competition is to demonstrate the power of the leading tools in each of these areas.
The competition will be affiliated with the International Workshop on Termination (WST 2026, https://termination-portal.org/wiki/21st_International_Workshop_on_Termination), which takes place at the Federated Logic Conference (FLoC 2026, https://www.floc26.org). It will be run on the RWTH University HPC cluster. The final run will be in parallel to the FLoC workshops on July 24th and 25th. The results will be presented at WST, and presumably also at IJCAR.
We strongly encourage all developers of termination and complexity analysis tools to participate in the competition. We also welcome the submission of termination and complexity problems, especially problems that come from applications.
A category is only run in the competition if there are at least 2 participants, at least 40 examples for this category in the underlying termination problem data base, and clearly defined rules. If there is no category that is convenient for your tool, you can contact the organizers, since other categories can be considered as well if enough participants are guaranteed.
For further information, we refer to the website of the termination and complexity competition: https://termination-portal.org/wiki/Termination_Competition_2026

If there is no category that is convenient for your tool, you can contact the organizers, since other categories can be considered as well if enough participants are guaranteed.
For further information, we refer to the website of the termination and complexity competition: https://termination-portal.org/wiki/Termination_Competition_2026
Important dates
Tool and Benchmark Submission: June 26
Full Run: July 13-17
Live Run: July 24/25

[Caml-list] MFCS 2026 - First Call for Papers
========================================================
MFCS 2026 - First Call for Papers
========================================================
The 51th conference on Mathematical Foundations of Computer Science (MFCS) will take place in:
Paris, France August 24th-28th, 2026
MFCS is among the conferences with the longest history in the field — the first conference in the series was held already in 1972. Traditionally, the conference moved between the Czech Republic, Poland, and Slovakia; since 2013, the conference has traveled around Europe.
The conference will be preceded, on August 23, by the Young Research Forum Workshop intended for students and postdocs.
NEW: Up to 10 papers will be accepted by the program committee, for which no presence onsite is required.
========================================================
Important dates and information
========================================================
Submissions: April 24th, 2026
Author notification: June 19th, 2026
Camera-ready version: June 26th, 2026
Conference: August 24th-28th, 2026 (YRF Workshop on August 23rd, afternoon)
Deadlines are firm; late submissions will not be considered. All dates are AoE.
Conference website: https://mfcs2026.irif.fr/
========================================================
Submission guidelines
========================================================
1) Papers must present original research on the theory of computer science. No prior publication and no simultaneous submission to other publication outlets (either a conference or a journal) is allowed. Authors are encouraged to also make full versions of their submissions freely accessible in an on-line repository such as arXiv.
2) Submissions take the form of an extended abstract of up-to 12 pages (LIPIcs document class), excluding title page, references and a clearly labelled appendix. The appendix may consist either of omitted proofs or of a full version of the submission, and it will be read at the discretion of program committee members. The extended abstract has to present the merits of the paper and its main contributions clearly, and describe the key concepts and technical ideas used to obtain the results. Submissions must provide the proofs which can enable the main mathematical claims of the paper to be verified.
3) Submissions authored or co-authored by members of the program committee are allowed.
4) At the time of submission, authors may declare that they are unable to attend the conference in Paris and therefore cannot give an in-person presentation. This choice will not influence the evaluation of submissions by the Program Committee. The Program Committee will rank all papers irrespective of their presentation status. Approximately 80 papers will be selected for in-person presentation, and up to 10 papers will be accepted without presentation. All accepted papers will be published in the same proceedings. This option is intended for authors who wish to publish their results at the conference but, for various reasons (e.g., family or financial constraints), are unable to attend the conference in person.
5) At least one author of each accepted paper with presentation is expected to register for the conference, and give the talk in-person. At least one author of each accepted paper without in-person presentation is expected to register for the conference for a reduced fee, and for each such paper the authors are expected to provide a pre-recorded video of the paper presentation that will be made available on-line during the conference. (Pre-recorded videos of the other papers are optional.)
6) Papers authored only by students should be marked as such at the time of submission in order to be eligible for the best student paper award.
7) MFCS proceedings are published in the Leibniz International Proceedings in Informatics (LIPIcs) series. The camera-ready version of accepted papers will need to comply with the LIPIcs style.

[Caml-list] Call For Papers: 6th Workshop on Program Equivalence and Relational Reasoning (PERR2026 @ CAV/FLOC)
[with apologies for cross-postings]
======================================================================
6th Workshop on Program Equivalence and Relational Reasoning
24 July 2026 at ISCTE campus, Lisbon, Portugal
associated with CAV 2026 at FLOC 2026
======================================================================
Submission Deadline: Friday, 24 April, 2026 (AoE)
Submit at: https://submissions.floc26.org/perr
CALL FOR PAPERS/PRESENTATIONS
PERR is an annual international workshop dedicated to the formal verification of program equivalence and related relational problems. It is the 6th in a series of meetings that bring together researchers from different areas interested in equivalence and related questions. PERR 2026 will be a workshop at FLOC 2026, and a satellite event to CAV 2026.
Program equivalence is arguably one of the most interesting and at the same time important problems in formal verification. It is a cross-cutting topic that has attracted the interest of several research communities: the field of denotational (game) semantics, deductive software verification, bounded model checking, specification inference, software evolution and regression testing, etc.
The goal of the workshop is to bring researchers of the different fields in touch and to stimulate an exchange of ideas leading to forging a community working on PERR. It welcomes contributions from the topics mentioned above but is also open to new questions regarding program equivalence. This includes related research areas of relational reasoning like program refinement or the verification of hyperproperties, in particular of secure information flow.
- regression verification
- program equivalence
- equivalence of higher order programs
- product programs, relational calculi
- verification of hyperproperties
- program refinement, refinement calculus
- specification of differences between programs
- inferring semantic differences between programs
- transformation validation
- correct compiler transformations
- automata bisimulation
- AI-supported equivalence checking
- relational properties of AI-based systems
- code equivalence checking in teaching and marking
This is an informal workshop that welcomes work in progress, overviews of more extensive work, programmatic or position papers and tool presentations.
SUBMISSION GUIDELINES
We invite two types of submissions:
- Regular papers. Regular papers should be at most 15 pages (excluding references). They should present original research results, tools, or case studies.
- Extended Abstracts. Extended abstracts should be at most 3 pages (excluding references). They should introduce work that has recently been published or is under review, or work in progress.
Submissions should be made using the PERR 2026 submission site:
Submissions must be a single PDF file, in LNCS format.
The workshop will have informal proceedings, posted on the webpage, and speakers will be asked to consider submitting papers towards a post-proceedings volume.
IMPORTANT DATES
Submission Deadline: Friday, 24 April, 2026 (AoE)
Notification: Thursday, 28 May, 2026
Workshop: Friday, 24 July, 2026
